ipaccess-config: Remove unused function ipaccess_bts_handle_ccm()

This function actually slippted in unintentionally when copying the
ipaccess driver from libosmo-abis.git as a base for the ipaccess-config
driver.
That function is actually not used either by libosmo-abis driver, but
was left there as a backward compatible API.
